Abstract
Thick target yield of the H-2 (d, p)(3) H reaction has been measured at very low energies under ultra-high vacuum conditions using deuteron-implanted Zr targets. Increase of enhancement factors observed for lowering deuteron energies could not be explained only by the electron screening effect. Assuming an additional contribution resulting from a single-particle threshold resonance, we are able to describe the energy dependence of the experimental reaction yield correctly. The theoretical calculations performed within the T-matrix approach allows also to study interference effects between different reaction amplitudes and predict a saturation of the threshold resonance strength at deuteron energies below 5 keV.
